using custom font inside C# .net core application

Question

I have the following code in my C# application that coverts text to image. In this code, I am using a custom font. I am specifying the path of the custom font, the custom font resides in my wwwroot folder. below is the code where I am using custom font.

string fontFam = Path.Combine(_environment.WebRootPath, "Font");

fontfam = fontfam + "\" + "journal.ttf";

graphics.DrawString(text, new Font(fontfam , 100, FontStyle.Regular), new SolidBrush(Color.FromArgb(0, 0, 255)), new PointF(0.4F, 2.4F));

below is where custom font resides:

I am passing the path to customfont in fontfam, but when I convert the text to image, the font is "Microsoft Sans Serif" and I can see the name Microsoft Sans serif in below screen too:

How can I make the font "Journal" in the C# code.

Hi @Anjali Agarwal ,

If you use System.Drawing, then you need to install this font in your computer. in the msdn documents on the Font Class you can see: If you attempt to use a font that is not supported, or the font is not installed on the machine that is running the application, the Microsoft Sans Serif font will be substituted.

You can copy your journal.ttf file to the computer's C:\Windows\Fonts directory, which will install your fonts on the computer.

In addition, Font cannot recognize the path, it can only recognize the corresponding familyName:

So you just need to pass the name of the font after installing it:

new Font("Journal", 100, FontStyle.Regular)

Result:

If you don't want to install fonts, and just want to get fonts through the corresponding path, you can use GrapeCity.Documents.Imaging Nuget Package. Below is mt test code, you can refer to it.

//Create GcBitmap
var bmp = new GcBitmap(1024, 1024, true, 96, 96);
//Create a graphics for drawing
GcBitmapGraphics g = bmp.CreateGraphics();

//Add a radial gradient
RadialGradientBrush r = new RadialGradientBrush(Color.Beige,
Color.RosyBrown, new PointF(0.5f, 0.5f), true);

//Draw a rectangle
var rc = new RectangleF(0, 0, bmp.Width, bmp.Height);

//Fill the rectangle using specified brush
g.FillRectangle(rc, r);

// Create a text format for the "Hello World!" string:
TextFormat tf = new TextFormat()
{
    Font = Font.FromFile(Path.Combine(_environment.WebRootPath, "Font/JOURNAL.TTF")),
    FontSize = 36
};

//Draw the string (text)
g.DrawString("Hello World!", tf, rc, TextAlignment.Center,
        ParagraphAlignment.Center, false);

//Save bitmap
bmp.SaveAsJpeg(Path.Combine(_environment.WebRootPath, "Image/Helloworld.jpg"));

Result:
